SLC 5/02 plc with 1746HSCE Card

SLC 5/02 plc with 1746HSCE Card

SLC 5/02 plc with 1746HSCE Card

(OP)
Hi,
I have been asked to modify a machine as follows.
On site there is a SLC 5/02 plc (1996), with spare slots.
I am using RS logix 500 V5.20 software. I know its a bit old but it works.
I have been asked to add the 1746HSCE card and connect an AB 845 diff encoder.
This is to measure the distance between products coming down the line.
The current system is inaccurate.
I have been on the Rockwell site but the info is not that clear.
All I want to do is measure a number of pulses, send an internal flag to initiate an output, then reset and start all over again.
ie.. Count pulses to product1, initiate internal flag/output, reset, Count pulses to product2 etc.....
This may sound pretty simple stuff to you guys, but hey we all live and learn.
I would be grateful for any advice / guidance on the above , and if possible a bit fo ladder logic,and any other set up information that I may need.
Also from the manuals I can see where I connect the A,A-,B,B- and Z,Z- but it is not clear where I connect the +5vdc and 0Vdc comm. at the 1746HSCE card.
Any help is gratefully received.
Regards,
mrbj

Thanks jde777,
I have looked at the info and it is pretty thorough.
However I am still unsure whether or not I need a seperate power supply for the encoder, or does it derive its' power from the 1746HSCE card.
Regards,
mrbj
